Description

CROSS REFERENCE TO RELATED APPLICATIONS

This application claims priority to U.S. provisional patent application Ser. No. 61/590,227, filed on 24 Jan. 2012, which is hereby incorporated hereinto by reference as if fully restated herein.

FIELD OF THE INVENTION

The present invention relates containers and/or trays and, and particularly to containers and/or trays and made of paperboard. More particularly, the present disclosure relates to a sturdy container or tray made of corrugated material and configured to contain food or other items.

BACKGROUND OF THE INVENTION

Containers made of paperboard, i.e., corrugated cardboard, are commonly used in the produce industry to pack, store and ship fresh produce. These containers typically have a bottom, opposite side walls, opposite end walls, and an open or partially open top, and when filled with fresh produce are placed on a pallet for shipping and handling. These containers have an inside minor flap which is divided, and shared with an outside full depth flap, to provide four additional corners in the same amount of material as other shipping containers. To enable the containers to be stacked on one another in stable relationship, they must have sufficient structural strength and rigidity to withstand the stacking forces. Thus, the side and/or end walls of the containers are usually constructed with multiple thicknesses, and/or additional reinforcing structure also may be provided, and the flutes of the corrugated material are typically arranged to extend vertically.

There is need for a paperboard container that is stackable, structurally rigid, and easy to set-up, reliably remains in set-up condition, and requires a minimum amount of material in its construction.

SUMMARY OF THE INVENTION

The present octagonal flush end container/tray is developed to address shallow tray design and yet could still benefit from eight corners cross laminated design. The container/tray has an inner minor flap feature that incorporates a mitered-bridging portion to have enough material to affect a seal and result in a strong container/tray. In the present invention, the top flap and outer flaps move inward so that the exterior wrap around corner mated with the mitered portion, rather than the flat end of the container/tray. This results in an oversized slot in the shape of a rhombus rather than rectangular. The present octagonal flush end container/tray did not have the overlapping corner flaps on the end, so that some of the material lying in the area in between (shaped slot) might be used in the construction of the container/tray rather than being discarded as scrap. Utilization of this material reduces its waste at the box plant and provides the customer with more of the material they are purchasing in the area of the blank. In addition to the improved blank utilization, it was found that adding some of the material back to the large slotted area improves stacking strength since this material is sandwiched between the inner anchor flap bridging section and the canopy auxiliary flap. Compression test comparing two octagonal containers/trays found that the octagonal container/tray with the sandwiching flap bridging section and outer auxiliary flap has at least between 8 to 12 percent higher stacking strength than the octagonal container/tray without the aforementioned configuration.

An article-transport container or tray is adapted to transport food or other articles from one site to another. The container includes a floor, a left-side closure, a right-side closure, a front end wall coupled to the floor and to the two closures, and a rear end wall coupled to the floor and to the two closures. These walls and closures cooperate to form an interior article-receiving region.

In illustrative embodiments, the container further includes a first tri-layer corner formed between the front end wall and the right-side closure. The first tri-layer corner includes an inner layer coupled to the front end wall, a medial layer formed from a first portion of the right-side closure, and an outer layer formed from a second portion of the right-side closure. The medial layer is positioned to lie between the inner and outer layers and is configured to provide means for interconnecting the outer layer and the inner layer to cause stacking strength of the container to be improved while minimizing scrap produced during blank forming so that costs associated with producing the container are minimized.

In illustrative embodiments, the medial layer includes corrugation. The corrugation is arranged to extend horizontally parallel to the floor of the container.

Additional features of the present disclosure will become apparent to those skilled in the art upon consideration of illustrative embodiments exemplifying the best mode of carrying out the disclosure as presently perceived.

DETAILED DESCRIPTION OF THE INVENTION

An erected article-transport container 10 in accordance with the present disclosure is shown in FIG. 1. Article-transport container 10 includes four tri-layer corners 21, 22, 23, 24 in accordance with a first embodiment of the present disclosure and first tri-layered corner 21 is shown in FIG. 2. Article-transport container 10 includes, in series starting in the front left, a front end wall 12 coupled to a floor 14 included in container 10, a left side closure 16 coupled to floor 14 and including a left canopy 70L overlying floor 14, a rear end wall 18 coupled to floor 14, and a right side closure 20 coupled to floor 14 and including a right canopy 70 overlying floor 14. Front end wall 12, left side closure 16, rear end wall 18, right side closure 20, floor 14, and tri-layer corners 21, 22, 23, 24 cooperate to define an interior region 26 therebetween that is adapted to receive articles (not shown) therein. Another embodiment of a tri-layer corner 221A is shown in FIGS. 10-12.

Tri-layer corners 21, 22, 23, 24 cooperate to provide means for increasing stack strength of container 10 while simplifying blank forming and minimizing scrap produced during blank forming. As an example, first tri-layer corner 21 includes an outer layer 211, a medial layer 212, and an inner layer 213 as shown in FIG. 2. Medial layer 212 is positioned to lie between outer layer 211 and inner layer 213 and is configured to provide means for interconnecting outer layer 211 and inner layer 213 to cause stack strength of container 10 to be improved while minimizing scrap produced during blank forming so that costs associated with producing container 10 are minimized.

Container 10 is made from a blank 28 after blank 28 is formed in a blank-forming process. As shown in FIG. 3, blank 28 includes floor 14, left side closure 16 appended to floor 14 along a left-side fold line 30, right side closure 20 appended to floor 14 along a right-side fold line 32, rear end wall 18 appended to floor 14 along a rear-end fold line 34, and front end wall 12 appended to floor 14 along a front-end fold line 36. Right side closure 20, left side closure 16, rear end wall 18, front end wall 12, and tri-layer corners 21, 22, 23, 24 cooperate to form a border coupled to floor 14 and arranged to cooperate with floor 14 to define interior region 26 of container 10.

Rear end wall 18 cooperates with left side closure 16 and right side closure 20 to establish a rear end 38 of container 10 as shown in FIG. 1. Front end wall 12 cooperates with left side closure 16 and right side closure 20 to establish a front end 40 of container 10 as shown in FIG. 1. It is within the scope of the present disclosure to make blank 28 from a variety of materials including corrugated paperboard, folding carton, and solid fiber and other materials such as plastic sheeting and corrugated plastic.

Article-transport container 10 is established as result of passing blank 28 through a container-forming process shown, for example, in FIGS. 4-9. As shown in FIG. 3, blank 28 includes floor 14, a front end strip 42 coupled to floor 14 along front-end fold line 36, left side closure 16 coupled to floor 14 along left-side fold line 30, a rear end strip 44 coupled to floor 14 along rear-end fold line 34, and right side closure 20 coupled to floor 14 along right-side fold line 32 as shown in FIG. 4.

Front end strip 42 illustratively includes front end wall 12, a first front anchor flap 46 coupled to front end wall 12 about a first front anchor-flap fold line 48, and a second front anchor flap 50 coupled to front end wall 12 about a second front anchor-flap fold line 52 as shown in FIG. 3. First front anchor flap 46 is positioned to lie in spaced-apart relation to second front anchor flap 50 to locate front end wall 12 therebetween. As shown in FIGS. 2 and 6, a portion of first front anchor flap 46 is used to establish inner layer 213 of first tri-layer corner 21. Similarly, a portion of second front anchor flap 50 is used to establish inner layer 223 of second tri-layer corner 22.

First front anchor flap 46 includes a front right corner bridge 90 that is coupled to front end wall 12 about a first front anchor-flap fold line 48 and a front right anchor tab 94 that is coupled to front right corner bridge 90 about a first front anchor-tab fold line 96 as shown in FIG. 3. Inner layer 213 of first tri-layer corner 21 is established during an initial stage of container forming as suggested in FIGS. 4-9.

During the initial stage of container formation, front end strip 42 is folded about front-end fold line 36 toward floor 14. At the same time, front right corner bridge 90 is folded inwardly toward floor 14 about first front anchor-flap fold line 48 and front right anchor tab 94 is folded inwardly toward floor 14 about first front anchor-tab fold line 96. As a result, front end strip 42 is arranged to extend upwardly away from floor 14 and front right anchor tab 94 is arranged to extend along right-side fold line 32. Front right corner bridge 90 is arranged to extend between and interconnect front right anchor tab 94 and front end wall 12.

Right side closure 20 illustratively includes a right inner strip 54 coupled to floor 14 about right-side fold line 32 and a right outer anchor strip 56 coupled to right inner strip 54 about a right anchor-strip fold line 58 as shown in FIG. 3. Right inner strip 54 includes, for example, a right side wall 60, a first right wall anchor flap 62 coupled to right side wall 60 about a first right wall flap fold line 64, and a second right wall anchor flap 66 coupled to right side wall 60 about a second right wall flap fold line 68 as shown in FIG. 3. First right wall anchor flap 62 is used to establish medial layer 212 of first tri-layer corner 21. Medial layer 212 of first tri-layer corner 21 is established during a subsequent stage of container forming as suggested in FIGS. 4-9.

During the subsequent stage of container forming, right side closure 20 is folded about right-side fold line 32 toward floor 14 so that right side wall 60 and first and second right wall anchor flap 62, 66 extend upwardly away from floor 14 as shown in FIG. 5. At the same time, first and second right wall anchor flaps 62, 66 are folded inwardly toward floor 14 about associated right wall flap fold lines 64, 68. As an example, first right wall anchor flap 62 is arranged to extend away from right side wall 60 toward front end wall 12 and is coupled to front right corner bridge 90 and form medial layer 212 as shown in FIGS. 2 and 7.

Right outer anchor strip 56 includes a right canopy 70, a first right primary canopy anchor flap 72, a first right auxiliary canopy anchor flap 74, a second right primary canopy anchor flap 76, and a second right auxiliary canopy anchor flap 78 as shown in FIG. 3. Right canopy 70 is coupled to right side wall 60 about right anchor-strip fold line 58. First right primary canopy anchor flap 72 is coupled to right canopy 70 by a first right primary flap fold line 80. First right auxiliary canopy anchor flap 74 is coupled to first right primary canopy anchor flap 72 by a first right auxiliary flap fold line 84 as shown in FIG. 3. Second right primary canopy anchor flap 76 is coupled to right canopy 70 by a second right primary flap fold line 86. Second right auxiliary canopy anchor flap 78 is coupled to second right primary canopy anchor flap 76 by a first right auxiliary flap fold line 88 as shown in FIG. 3. Outer layer 211 of first tri-layer corner 21 is established during a last stage of container forming as suggested in FIGS. 8 and 9.

During the last stage of container forming, right outer anchor strip 56 is folded about right anchor-strip fold line toward floor 14 so that right canopy 70 is arranged to lie in spaced-apart parallel relation above floor 14 as shown in FIG. 2. At the same time, first right primary and auxiliary canopy anchor flaps 72, 74 are folded downwardly about first right primary flap fold line 80 so that first right primary canopy anchor flap 72 extends downwardly and mates with front end wall 12 as suggested in FIG. 7 and shown in FIG. 8. Finally, first tri-layer corner 21 is established as a result of folding first right auxiliary canopy anchor flap 74 about first right auxiliary flap fold line 84 toward first right wall anchor flap 62 as suggested in FIG. 8 and shown in FIG. 9.

First tri-layer corner 21 is established as a result of coupling first right wall anchor flap 62 to front right corner bridge 90 and by coupling first right auxiliary canopy anchor flap 74 to first right wall anchor flap 62 as shown in FIGS. 6-9. As an example, first right wall anchor flap 62 is coupled to front right corner bridge 90 by adhesive 98 as shown in FIG. 6. First right auxiliary canopy anchor flap 74 is coupled to first right wall anchor flap 62 by adhesive 100 as shown in FIGS. 7 and 8. While adhesive 98, 100 is shown as an example, any other suitable alternative may be used.

In an illustrative embodiment, the corrugation of blank 28 is positioned to run in a transverse direction TD as shown in insert A in FIGS. 1, 3, and 4. As a result, inner and outer layers 211, 213 of tri-layer corners 21, 22, 23, 24 have corrugation which runs vertically as shown in FIG. 6 after container 10 has been formed. Medial layer 212 has corrugation which runs horizontally as shown in FIG. 6 after container 10 has been formed. In one illustrative example, it was found surprisingly that the medial layers of tri-layer corners 21, 22, 23, 24 increases stacking strength of container 10 as compared to those containers lacking medial layer 212. Stacking strength may be measured using standard industry test methods. As an example, stacking strength was evaluated using the TSL-8.2-WI-005 test method and procedure reference T804 of the Technical Association of the Pulp and Paper Industry (TAPPI).

As illustrated in FIG. 3, floor 14 has an octagon shape that includes in series, a first mitered edge 102, a front end edge 104, a second mitered edge 106, a left edge 108, a third mitered edge 110, a rear end edge 112, a fourth mitered edge 114, and a right edge 116. As an illustrative example, left and right edges 108, 116 have lengths greater than lengths of front and rear end edges 104, 112. Front and rear end edges 104, 112 have lengths greater than first, second, third, and fourth mitered edges 102, 106, 110, 114. Edges 102, 104, 106, 108, 110, 112, 114 cooperate to define a floor perimeter 92 as shown in FIG. 3.

First tri-layer corner 21 is arranged to extend between front end wall 12 and right side wall 60 and lie at an angle 118 relative to front end wall 12 as shown in FIG. 2. Angle 118 is defined to be between first mitered edge 102 of floor 14 and front end edge 104 of floor 14. As shown in FIG. 2, angle 118 is illustratively an acute angle. Inner layer 213 of tri-layer corner 21 is positioned to lie inside floor perimeter 92 and is arranged to extend between front end edge 104 and right edge 116 and between floor 14 and right canopy 70. Medial layer 212 is positioned to lie outside floor perimeter 92 is and is arranged to extend along first mitered edge 102 so that medial layer 212 lies at angle 118. Outer layer 211 is positioned to lie outside floor perimeter 92 and is arranged to lie in spaced-apart relation to first mitered edge 102 to cause medial layer 212 to lie there between.

Blank 28 is formed during an illustrative blank forming process, for example in a manufacturing facility. During the blank forming process, a corrugated sheet is processed to establish blank 28 and scrap which separated from blank 28. During blank forming, first right wall anchor flap 62 is formed to have a proximal end 62P and a distal end 62D which is spaced-apart from proximal end 62P. First right wall anchor flap 62 is appended to right side wall 60 along first right wall flap fold line 64 by proximal end 62P. As shown in FIG. 3, first right wall anchor flap 62 extends away from first right wall flap fold line 64 toward first front anchor flap 46 and first right auxiliary canopy anchor flap 74 such that distal end 62D is spaced apart from first front anchor flap 46 and first right auxiliary canopy anchor flap 74.

During the blank forming process which may be performed in a manufacturing facility, scrap is separated from blank 28 which causes two triangle-shaped apertures 120A, 120B and an interconnecting rectangle-shaped aperture 120C to be formed therein. As a result of the scrap piece being monolithic, it simplifies removal and separation from blank 28. Another result of distal end 62D being spaced apart from first front anchor flap 46 and first right auxiliary canopy anchor flap 74 is that rectangle-shaped aperture 120C is formed by removing scrap. Container forming is simplified as a result of distal end 62D of first right wall anchor flap 62 being spaced-apart from first front anchor flap 46 and first right auxiliary canopy anchor flap 74 is that friction between distal end 62D of and first front anchor flap 46 and first right auxiliary canopy anchor flap 74 is eliminated. Because friction has been eliminated, the likelihood of forming improperly formed containers is minimized.

Also during blank forming, a first crush area 121 is formed in blank 28. First crush area 121 is configured to provide means for minimizing friction developed between front right anchor tab 94 and first right auxiliary canopy anchor flap 74 during container forming as front right anchor tab 94 of front end strip 42 is folded upwardly about front-end fold line 36. Second, third, and fourth crush areas 122, 123, 124 are also formed.

First, second, third, and fourth crush areas 122, 123, 124 are substantially similar to first crush area 121, and thus, only first crush area 121 will be discussed in detail. First crush area 121 is established along a cut line 125 formed between front right anchor tab 94 and first right auxiliary canopy anchor flap 74 as shown in FIG. 3. A rate of container forming may be increased as a result of minimizing friction which decreases the likelihood of improperly forming containers. These improperly formed containers are also called as cripples. Blank 28 and resulting container 10 minimize waste because the number of improperly formed containers is minimized.

A portion of a blank 218 of corrugated material in accordance with a second embodiment of the present disclosure is shown in FIG. 10 and can be assembled as suggested in FIG. 10 to produce a first tri-layer corner 221A of a container 210 as shown in FIG. 12. In most respects, blank 218 is similar to blank 28 of FIG. 3.

Blank 218 includes floor 14, a right side closure 220 appended to floor 14 along right-side fold line 32, and a front end strip 42 appended to floor 14 along front-end fold line 36 as shown in FIG. 10. Right side closure 220 and front end strip 42 are configured to be folded in a manner similar to that shown in FIGS. 4-9 to produce first tri-layer corner 221A.

As discussed previously, first tri-layer corner 221A includes outer layer 211, a medial layer 2212, and inner layer 213 as shown in FIGS. 11 and 12. Inner layer 213 is provided by front right corner bridge 90 of front end strip 42 and is established during initial folding of blank 218. Medial layer 2212 is provided by a first right wall anchor flap 262 included in right side closure 220 and is established during the subsequent folding of blank 218. Outer layer 211 is provided by first right auxiliary canopy anchor flap 74 and is established during the final folding of blank 218.

Right side closure 220 illustratively includes a right inner strip 254 coupled to floor 14 about right-side fold line 32 and right outer anchor strip 56 coupled to right inner strip 254 about right anchor-strip fold line 58 as shown in FIG. 10. Right inner strip 254 includes, for example, right side wall 60, a first right wall anchor flap 262 coupled to right side wall 60 about first right wall flap fold line 64, and a second right wall anchor flap (not shown) coupled to right side wall 60 about second right wall flap fold line (not shown). First right wall anchor flap 262 establishes medial layer 2212 of first tri-layer corner 221A. Medial layer 2212 of first tri-layer corner 221A is established during the subsequent stage of container 210 in a manner similar to that of container 10 suggested in FIGS. 4-9.

Blank 218 is formed during an illustrative blank forming process in which a corrugated sheet is processed to establish blank 218 and scrap which is separated from blank 218. During blank forming, first right wall anchor flap 262 is formed to have a proximal end 262P and a distal end 262D which is spaced-apart from proximal end 262P. First right wall anchor flap 262 is appended to right side wall 60 along first right wall flap fold line 64 by proximal end 262P. As shown in FIG. 10, first right wall anchor flap 262 extends away from first right wall flap fold line 64 toward first front anchor flap 46 and first right auxiliary canopy anchor flap 74 such that distal end 262D abuts first front anchor flap 46 and first right auxiliary canopy anchor flap 74. Distal end 262D is separated from first front anchor flap 46 and first right auxiliary canopy anchor flap 74 by a cut line 142 as shown in FIG. 10.

During blank forming, scrap is separated from blank 218 which causes two triangle-shaped apertures 120A, 120B to be formed therein. In comparison to blank 28, blank 218 lacks rectangle-shaped aperture 120C thus causing triangle-shaped apertures 120A, 120B to be separate from one another. As a result of distal end 262D of first right wall anchor flap 262 abutting first front anchor flap 46 and first right auxiliary canopy anchor flap 74, friction is developed during container forming as front end strip 42 is folded upwardly about front-end fold line 36. A first right-wall anchor-flap crush area 144 which is established during blank forming to provide means for minimizing friction developed between first right wall anchor flap 262 and first front anchor flap 46 and first right auxiliary canopy anchor flap 74 during container forming so that the likelihood of creating improperly formed containers is minimized.

In an illustrative embodiment, the corrugation of blank 218 is positioned to run in a transverse direction TD as shown in insert 2A in FIG. 10. As a result, inner and outer layers 211, 213 of tri-layer corner 221A has corrugation which runs vertically as shown in FIG. 12 after container 210 has been formed. Medial layer 2212 has corrugation which runs horizontally as shown in FIG. 10 after container 10 has been formed. In one illustrative example, it was found surprisingly that the medial layer 2212 of tri-layer corner 221A increases stacking strength of container 210 about 7%. Stacking strength may be measured using standard industry test methods. As an example, stacking strength was evaluated using the TSL-8.2-WI-005 test method and procedure reference T804 of the Technical Association of the Pulp and Paper Industry (TAPPI).

In another embodiment, the right canopy and the left canopy may be configured so as to establish a lid after the container has been formed. In an example, the right canopy has a width about equal to one half a width of the floor and the left canopy has a width about equal to one half the width of the floor. After the container has been erected, the right canopy is folded inwardly toward the floor about the right anchor-strip fold line so that the right canopy lies above the floor and extends away from the right side wall toward the left sidewall. The left canopy is also folded inwardly toward the floor about the left anchor-strip fold line so that the left canopy lies above the floor and extends away from the left side wall toward the right side wall. As a result, the interior region is defined by the floor, the right side closure, the left side closure, the front end wall, the rear end wall, the four tri-layer corners, and the lid established upon completion of forming the container.

In another embodiment, a container further includes a front canopy and a rear canopy. The front canopy is coupled to the front end wall about a front-canopy fold line. The rear canopy is coupled to the rear end wall about a rear-canopy fold line. After forming of the container, the front canopy lies in a plane positioned to lie between the right canopy and the floor. The rear canopy lies in a plane that is positioned to lie between the left canopy and the floor. The rear canopy, front canopy, left canopy, and right canopy cooperate to establish a framed top of the container.
